Babel trouble: column names, arguments, and R dataframes

[Christian Moe <mail@christianmoe.com>]

Hi,

I'm having odd troubles with reading tables into R as dataframes with 
named vectors. Unfortunately I have difficulties pinning down a 
consistent problematic behavior. But one weird example follows below:

I have two tables, data1 and data2.

The first test reads data1 in as a dataframe named `values', and 
returns that dataframe, spitting out the identical table again. This 
is the behavior I expect.

The second test passes both tables as arguments. It's supposed to 
return the first table, just as the first test did -- and it returns 
the correct values, but the column names have been swapped with those 
in the second table! The third test, similarly, returns the second 
table, but with the colum names of the first table.

Any hints?

Yours,
Christian
